Imagine this becoming a thing. Where anyone could eventually become Estonia's resident with all the rights (and of course responsibilities) equal to the people actually living there. Once other nations would follow, then the borders would truly start to disappear because it wouldn't really matter where you are located. No more us and them, just people of the earth.<p>I know it's way too optimistic and this solution probably introduces just as many problems as it solves, but still, one is allowed to dream, right?
